Abstract

In the last years the interest in 2D and 3D spatial data grew, reaching many application areas (such as built heritage documentation, urban planning and design, risk prevention management, smart and resilient cities design, energy-related plans, multicriteria analysis and so on). Moreover, many researches deal with integration and linked data structures with a top-down approach, considering the data models. In this framework, the link among standards for 3D representation of cities and heritage and semantic web has been increased in order to enhance geometric and semantic interoperability among data. However, the road towards an effective standardization, with universal consensus and fitting the requirements of any customized use case is still very long. On the other hand, the importance of data reuse and integration is becoming fundamental due to the huge amount of data available (mostly heterogeneous, collected with different techniques and methods with a different scale and stored with different data structures and with different aims). Therefore, a unique mechanism for accessing them would be helpful for many users and actors. In this context, the aim of the present research focuses on the analysis of various data models, ontologies and thesaurus to investigate and to clarify how different concepts and attributes of the selected datasets could be expressed and represented by other conceptualisations and data specifications. The purpose is to facilitate the integration with other geospatial datasets. Hence, the paper investigates a strategy and a methodology to re-use available datasets even when not completely described by one only data model.
